A new reversed field pinch (RFP) device with a very small aspect ratio (A=2.1), TPE-QS was constructed, and here are reported the first results of plasma experiment. The aspect ratio, A=2.1 is much smaller than those of conventional devices (A>=3). At this small A, rational surfaces appear more diversely in the core region. The minimum toroidal mode number of n=4 appears near at the mid-radius. The toroidal loop voltage Vloop will also be lowered because of smaller toroidal path. The device was designed by minimizing A after some technical scaling consideration and by q-profile calculation, and was constructed by re-use of old TPE-2M [1, 2]. The photograph of the device is shown in Fig. 1. The dimensions are summarized in Tab. 1. The RFP plasma experiment started in March 2004. The main diagnostics in the initial experiment are a magnetic pickup coil array on the inner surface of V/V, a toroidal flux loop array outside V/V, and visible and SX optics.
